Title: Synthesis of medium-membered ring ketone
Inventor: OOISHI TAKESHI
IPC: C07C315/04
Filed: 1979-07-09
Abstract: PURPOSE: To obtain the title compound, via two kinds of novel intermediates, by the treatment of a novel lactam sulfide produced from o-(methylamino)phenyl mercaptan, etc., as a starting material, with a peracid, a deprotonating agent, and a reducing agent through desulfurization and reduction.  
     CONSTITUTION: A novel lactam sulfide compound of formula I (n is an integer 8W12) produced from e.g. o-(methylamino)phenyl mercaptan or its dimer, is treated with a peracid, e.g. sodium periodate, to prepare a novel lactam sulfide of formula II, which is treated with a deprotonating agent, e.g. lithium diisopropylamide, to give a novel compound of formula III. The resulting compound is further desulfurized and reduced with a reducing agent, to give a medium-membered ring ketone of formula IV readily and in high yield.

Title: Energy subtraction picture generating method
Inventor: SHIMURA KAZUO
IPC: A61B6/00
Filed: 1991-04-18
Abstract: PURPOSE:To improve the granularity of an energy subtraction (ESu) picture by adding a high frequency component of a picture data accumulated on a stimulable phosphor sheet to the energy subtraction (ESu) picture. CONSTITUTION:A filter 6 cutting a radiation ray of a low energy is interposed between two upper and lower recording sheets 5 and 7 to separate a radioactive ray energy. Then a radioactive ray 3 radiates and only a radioactive ray with a high energy reaches the lower recording sheet 7. The radiation picture recorded on both the recording sheets 5, 7 is read and subtraction processing is implemented between the obtained picture data to obtain a subtraction picture. No subtraction processing is implemented for the high frequency component and the subtraction processing is implemented for the low frequency component. Thus, a stimulable phosphor sheet acts like the filter 6 cutting a low energy radioactive ray and a high frequency component of the picture data stored on the sheet 6 is added to the energy subtraction (ESu) picture to obtain the ESu picture whose granularity is improved.

Title: Air cleaner
Inventor: KAWAKAMI MASARU
IPC: B03C3/02
Filed: 1983-05-18
Abstract: PURPOSE:To provide an air cleaner adapted to utilize an ionic-flow, by allowing for the flow of ionic current between an ionization line and an opposing electrode and arranging a dust collecting electrode at its downstream so that the layer of activated charcoal or a dissolved ozone catalyst may be formed along the inner wall of passageway of supplying air. CONSTITUTION:Upon a voltage being applied between earth electrodes 12, 12' and the high-voltage electrode 13 of dust collecting section simultaneously with the application of high-voltage power between an ionization line 11 and earth electrodes 12, 12', an ionic-flow is generated for collecting dusts. The ionic-flow from the dust collecting section towards a lee side collides with a deflector 16 and an exhaust passage wall 17, and further flows along an activated charcoal layer or an ozone dissolved catalyst 19 formed on the wall. The ionic-flow is finally discharged through an exhaust port 15. An ozone floating in the ionic- flow is thus absorbed by the activated charcoal layer 19, and thereby lowering an ozone concentration without the reduction of gas volume due to an air flow.

Title: Motor-driven three-wheel type wheelchair
Inventor: KANEKO MITSURU
IPC: B62K5/02
Filed: 1990-03-31
Abstract: PURPOSE:To obtain the motor-driven three-wheel type wheelchair whose shock absorbing effect is large, and also, which can prevent in advance damage of a car body including a bumper by providing a damper on both sides of the front part of a car body frame, and supporting the bumper placed in front at a prescribed interval to the peripheral edge of the front wheel by the damper. CONSTITUTION:A motor-driven tricycle has a bumper 24 protruded in front of the front wheel 15, and when the bumper 24 comes into collision with an obstacle on the road, force F is applied to a damper piston 30 through the bumper 24. The damper piston 30 pushes a damper spring 26, and also, moves the bumper 24 to the rear and slides in a damper holder pipe 25 so as to reduce the shock force. Also, when stronger force F is applied to the bumper 24, the bumper 24 is pressed against a tire part of the front wheel 15. In this case, since the front wheel 15 hits against the center part of the bumper 24, the bumper 24 is reduced as to its bending moment, and also, the shock force is reduced by a cushion of the tire part. Moreover, the retreat of the bumper 24 is stopped finally by stopper rubber 28 of the inside of the damper holder pipe 25, but before that time, the force F is reduced greatly.

Title: Camera with automatic focusing device
Inventor: HAMADA MASATAKA
IPC: G03B3/00
Filed: 1986-04-16
Abstract: PURPOSE:To prevent a motor from bad influence upon its current consumption due to braking by inhibiting the output of a brake signal when a release signal is outputted before a photographing lens reaches focusing status. CONSTITUTION:When the quantity and direction of defocus are detected on the basis of a signal from a CCD image sensor FLM which is a focus detecting means, the photographing lens is driven by a driving signal outputted from an AF microcomputer MC1, and when the photographing lens reaches the focusing position, a driving motor MO1 is stopped and a brake signal is outputted. If a release signal is outputted before the photographing lens reaches the focusing position, the output of the brake signal is inhibited and the lens is moved by inertia. Consequently, the driving motor MO1 is not forcedly braked and the motor MO1 can be prevented from bad influence upon its current consumption due to braking.

Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To reduce a torque and facilitate manufacture by forming an axially extending recession on an inner periphery of a standing wall of a housing, and forming a clearance between the recession and an outer periphery of the bearing. SOLUTION: One end of a columnar member is drawin to form a reserved columnar main body and a reserved lever. The main body is axially pressurized to form a tapered surface near an outer periphery of the lever side end face. A standing wall 9 is extruded by pressing the vicinity of the axis of the other end by means of a punch. A recession 12 is formed on an inner periphery thereof by cutting process to provide a housing 6. A spherical head 4 of a ball stud 2 is inserted from an opening of a bearing 5. It is also inserted from an opening 7 of the housing 6. One end 13 of the housing 6 is caulked to the inner peripheral side to complete manufacture of a ball joint 1. Since a clearance is formed between the recession and an outer periphery of the bearing, a contact area between the housing and the bearing is reduced.  Pressing load from the housing to the bearing is reduced at the time of caulking to reduce a torque.

Title: Magnetic recording medium
Inventor: GOTOU SHIGETO
IPC: C10M105/36
Filed: 1984-05-02
Abstract: PURPOSE:To reduce the scratch of the magnetic layer of a magnetic tape due to excess tension applied to the tape and the exfoliation of dust by incorporating dibasic carboxylic acid monoester into the magnetic recording medium so as to improve the lubricating effect by addition by a small amount and to inhibit a blooming phenomenon. CONSTITUTION:This magnetic recording medium is characterized by the presence of a layer contg. dibasic carboxylic acid monoester. The dibasic carboxylic acid monoester shows a significant lubricating effect and bleeds out hardly because it is required to be added only by a small amount. The reason that the lubricating effect is shown is considered to be that the effect of fatty acid on magnetic powder and the effect of fatty acid ester on a binder are shown efficiently and harmoniously because the acid and ester are united to one body in one molecule. The magnetic recording medium has improved squareness and S/N ratios and reduces an output reduction or fluctuation and drop-out.
